The Holley GM 2x4 dual plane manifold is designed in the tradition of the great dual Holley 4160 induction systems that competed on drag strips, in Trans-Am at Lemans in the 1960's. The technology of the LS pushrod engine is now mated with the impressive multi-carb looks and performance of the muscle car era!

Features:

  • Power band from 1500-7000rpm
  • Perfect for any street/performance, muscle car or street rod enthusiast
  • Cast aluminum construction
  • Fits all GM LS Gen III or Gen IV engines equipped with LS3/L92 style rectangular port cylinder heads.
  • Dual plane design for equal distribution and great mid-range torque without comprimising top-end power
